ALFRED ROESOI'I, OF BROOKLYN, NENV YORK, ASSIGNOR OF TWO-THIRDS TO WVILLIAM B. VVADSWORTH, OF PLAINFIELD, AND FREDERICK H. DAVIS, OF ELIZABETH, NEW JERSEY.
AUTOMATIC HEAT REGULATOR.
SPECIFICATION formingpart of Letters Patent No. 583,632, dated June 1, 1897.
Application filed July 2 3, 1 89 6.
To all whom it may concern:
Be it known that I, ALFRED ROESCH, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Automatic Heat Regulators, of which the following is a specification.
My invention relates to improvements in air-controllin g valve mechanism for that class of heat -regulating systems in which compressed air is employed as the actuating power for opening and closing the steam-controlling valves and a thermostat is employed for operating the air-controlling valves.
The construction of my invention is explained by reference to the accompanying drawings.
Figure 1 illustrates a heat-regulating system with which my aircontrolling valve mechanism is adapted to be used. Fig. 2 is an enlarged view of the air-controlling valve mechanism shown in Fig. 1 in connection with the actuating-arm of a thermostat.
Like parts are referred to by the same'reference-letters in both views.
That the object and function of my aircontrolling mechanism may be more clearly understood, it is shown and described as arranged in connection with an air-reservoir and a steam-radiator.
A represents the air-controllin g mechanism proper, the function of which is to control the course of compressed air from the air-reservoir B both to and from the diaphragm-chamber C. The air-controlling mechanism A is actuated by the vibrating arm D of a therm'ostat, which arm is caused to move upward and downward as the temperature of the room is raised and lowered. When the arm D is raised, air is permitted to pass from the airreservoir B, through the air-controlling mechanism A, to the diaphragm-chamber C, and when said arm D moves downward the escape of air from the air-reservoir is cut off, when the air which has done its work in the diaphragm-chamberis permitted to pass back to the air-controlling mechanism A, from which it escapes.
Steam is admitted from a steam-generator Serial No. 600,317. (No model.)
to the steam-controlling valve E through the pipe F, when it passes therefrom to the steamradiator G through the steam-pipe H. The valve E is opened by the action of the spring- I and closed by air-pressure upon the dia phragm J within the chamber 0.
The passage of air from the air-reservoir to the diaphragm-chamber O is controlled by the valve K, which when in its normal condition closes the valve-seat L, but when said valve K is raised from its seat the compressed air passes from the air-reservoir B, through the pipe M, to the inlet or primary air-chamber N, thence to the secondary or outlet chamber 0, through the side duct P, thence to the diaphragmchamber O, through the pipe Q, when, acting through the diaphragm J, it closes said steam controlling valve. When by a change of temperature of the room the actuating-arm D is moved downward, it first permits the valve K to close, when it moves the valve R from its seat R, whereby the compressed air in the diaphragm-chamber O is permitted to' escape, whereby the diaphragm J is raised by the action of the spring I and the steam-controlling valve E is opened.
By a reverse movement of the arm D the valve R is first permitted to close, when the valve K is opened, as before described.
The arm D is connected at its free end with the respective valve-stems S and T of the aircontrolling valve through the branch arms a and 3 which branch arms are formed with loosely-fitting recesses or apertures for the reception of said stems. The outer ends of the stems S and T are each provided with bearing stops or nuts a a, against which the inner surfaces of said branch arms or and y are respectively brought to bear as said arm D is raised and lowered. Thus when the arm D moves downwardly the branch 14 engages the bearing stop or nut a of the upper valvestem, whereby the valve R is opened While the branch B moves freely over the lower valve-stem without communicating motion thereto, while by a reverse movement of the arm D the branch arm u moves freely over the upper valve-stem without moving it,while the lower branch g engages the bearing stop or nut to of the lower valve-stem, whereby the lower valve K is opened.
The valves K and R are preferably made of soft rubber or other elastic substanceavhich will permit of enough compression to open the ports or valve-seats they respectively bear against, and which in their normal condition they are adapted to close, while they at the same time react and bear against the inner walls of the respective chambers around the bearings of the respective valve-stems, and thus prevent the escape of air from such chambers around said valve-stems, whereby the ordinary stufling-boxes and packing usually employed around valve-stems are dispensed with.
It is obvious that by the peculiar construction and arrangement of the elastic air-controlling valves and the actuating branch arms connected with such valves one of said airvalves is always closed before the other is opened, whereby the loss of compressed air common with other forms of air-controlling devices is avoided.
Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is
1. In an air-controlling device for a heatregulating system, the combination of a primary or inlet air-chamber provided with an inlet air-duct; an inlet air-controlling valve located in said primary air-chamber adapted to control the admission of air thereto; a secondary or outlet air-chamber; an air-duct communicating between said primary and secondary air-chambers an air-duct communicating from said secondary air-chamber with a diaphragm-chamber of a steam-controllingvalve; an air-controlling valvelocated in said secondary air-chamber adapted to control the escape of air from said diaphragmchamber; each of said air-controlling valves being provided with protruding valve-stems a thermostatically-actuated arm communicatin g with the protruding stems of said aircontrolling valves, said thermostatically-actuated arm being adapted as it moves in either direction to engage the stems of and to actuate one of said air-controlling valves as the other is automatically closed substantially as and for the purpose specified.
2. In an air-controlling device for a heatregulating system the combination of a primary or inlet air-chamber provided with an inlet air duct; 23 secondary or outlet airchamber provided with an air-duct communicating with the diaphragm-chamber of a steam-controlling valve; an air-duct communicating between said primary and secondary air-chambers; two two-faced elasticair-controlling valves one located in each of said air-chambers and provided with protruding valve-stems one face of each of said two-faced elastic valves being adapted to close its seat and the other face to close the space between said stems and their bearing-walls and means for actuating said air-controlling valve substantially as and for the purpose specified.
In testimony whereof I aflix my signature in the presence of two witnesses.
ALFRED ROESCII.
